IMPROVEMENTJN WINDLASSES.

The Schedule referred 'co in theserLetters Patent and making part of che same.

To all whom it may concern: .Y

Be it known that we, Esos WMJERBUIW and GEORGE N. WATERBURY, of Stamford, in the count-y ot' Fairtield and State of Connecticut, have invented a new and uset'ul Improvement in Ships Windlass; and we do hereby declare' that the tbllowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to .the accompanying drawing forming part of this specification, in .which- Figure 1 is a front view of our improved-windlass, partly in section to showthe construction.

Figure 2 is a vertical cross-section of the same, taken through the line a: '96, tig. 1.

Similar let-ters otfreferei'ice indicate corresponding parts.

Oui' invention has for its object to improve the oon struction of a ships windlass in such a way as to make it much more convenient in use, it heilig so constructed as to allow Athe cable to be paid out freely, and which shall at the same time be simple in construction, and easily operated and controlled; and

It consists in the construction and combination of various parts, as hereinafter `more fully described.

A is the shaft, which revolves in bearings in the standards B, and to which the ratchet-wheel C- and the central ratchet-wheel D are securely attached.

E are the wheels to which are applied or upon which are formed the hars F, hy which the power is applied. The wheels E work loosely upon the shaftA; but their movement is limited by the forked or slotted projcctiiur G tirmly attached to them, and which projects tln'ough a short curved slot in the ratchet-wheels D.

The connection between the bar-wheels E and the ratchet-wheels D is further strengthened by pins, H, attached to said ratchet-wheels and projecting through short curved slots in the said bar-wheels E.

lare the drums about which the cable lis coiled, and which are placed upon and firmly secured to the sleeves J, or to the disks -or wheels K formed upon the inner ends of the said sleeves J. The sleeves J revolve loosely upon the shaft C.

The sides of the wheels K are recessed, or have anges formed around their outer edges to form recesscs in which are` placed the two curved bars oraround the shat't A, the two end parts of said lever being in line with each other, as shown in iig. 2. The free end of the lever M is placed in the fork or slot of the projection G.

N is a stop or rest attached to the ratchet-wheel O,

and which serves as a guide, stop, and fulcrnin to saidI lever.

0 is alight spring placed in the recess of the disks or wheels K, with its ends resting against the inner sides of the curved bars L,and which is designed "simply to hold the said bars in their places.

By this construction, when power is applied to the ratchet-wheels O, it is applied to the lever M by the stop or projection N, and the tendency is to spread the curved bars L, forcing their outer surfaces against the inner 1surface of the iiange oft-he wheel or disk K in the manuel' of a friction-clutch, so that the sleeve4 allel with the faces of the ends of the curved hars L,

thus releasing the wheel or disk, allowing the sleeve Jand drum l to revolve i'rcely, paying out the cable, its motion being readily regulated and controlled by means of thebar-'wheels E.

Having th'us described our invention, n XVe claim as new and desire to secure by.,Letters Patent- The combination of .the bar-wheelE, with its slotted projection G, ratchet-wheel O, lever M, curved bars L, recessed disk or Wheel K, and sleeve J, with each other and with the sha-'tA and drum I, substantially as herein shown and described, and for the purpose setforth.
